Making Mopar's supercharged Hellephant 426 HEMI crate engine feel at home inside a RAM TRX has been an ongoing project here at Hennessey. With the calibration phase of Hennessey's Hellephant-swap process complete, it was time to visit the Pennzoil Proving Ground to put this astounding 1000 HP truck through its paces.
